24,081. Dijk, H. N. van. Dec. 15, 1913, [Convention date]. Ploughs. - A machine for harvesting or digging sugar cane and other' plants, such as cassava, also applicable for making furrows, has its driving-gear so arranged that the tools are first caused to operate upon a length of soil while the machine remains stationary, and then the machine is advanced while the tools are still. The motor 3 is mounted on a frame 2 supported by two side wheels 4 and a steering- wheel 5. Supports 1, in which members 6 supporting a plough 35 or milling-cutters for loosening the soil move, are secured to the rear of the frame 2. The motor drives the shafts of two independent friction clutches 9, 10, the clutch 9 being adapted to transmit power to a shaft 11 which is connected through bevel-gearing 12 to gear-wheels 14 operating the running wheel 4. The wheels 14 operate through a pawl device, so that the wheels 4 may move independently. The clutch 10 couples up the shaft 15, which drives shafts 21, 24 through bevel-gearing, the shaft 21 being connected by chain - and - sprocket gearing with a shaft 27 on which two chain-wheels 28 are mounted, which each drive an endless chain 29a running over the rollers 29 on the end of the supports 1. Each of the chains 29a runs over two intermediate rollers 30 to a chain disk 31, thus operating the milling-cutter 36. The shaft 24 operates, through chain-and-sprocket gearing, a shaft 32, upon which are mounted two chain-wheels 33 driving chains passing over the rollers 34 and connected to the sliding toolsupports 6. The sprocket-wheels on the shafts 27, 32 a.re driven through pawls, so that the tools are not operated when the motor is moved forward. In operation, the clutch 10 is thrown in, thus causing the members 6 carrying the tools to be moved from one end of the supports 1 to the other, the carriage being held steady by means of a brake 39; the clutch 10 is then released and the clutch 9 put in, so that the machine is moved to bring a fresh stretch of ground below the supports 1. The Specification as open to inspection under Section 91 (3) (a) states also that one projecting tool support may be used; this subject-matter does not appear in the Specification as accepted.
